1. FIELD

Provided herein are methods of using (S)-2-(2,6-dioxopiperidin-3-yl)-4-((2-fluoro-4-((3-morpholinoazetidin-1-yl)methyl)benzyl)amino)isoindoline-1,3-dione, or an enantiomer, mixture of enantiomers, tautomer, isotopolog, or pharmaceutically acceptable salt thereof, in combination with a second active agent for treating, preventing or managing hematological malignancies.

2. BACKGROUND

Cancer is characterized primarily by an increase in the number of abnormal cells derived from a given normal tissue, invasion of adjacent tissues by these abnormal cells, or lymphatic or blood-borne spread of malignant cells to regional lymph nodes and metastasis. Clinical data and molecular biologic studies indicate that cancer is a multistep process that begins with minor preneoplastic changes, which may under certain conditions progress to neoplasia. The neoplastic lesion may evolve clonally and develop an increasing capacity for invasion, growth, metastasis, and heterogeneity, especially under conditions in which the neoplastic cells escape the host's immune surveillance. Current cancer therapy may involve surgery, chemotherapy, hormonal therapy and/or radiation treatment to eradicate neoplastic cells in a patient. Recent advances in cancer therapeutics are discussed by Rajkumar et al. in Nature Reviews Clinical Oncology 11, 628-630 (2014).

All of the current cancer therapy approaches pose significant drawbacks for the patient. Surgery, for example, may be contraindicated due to the health of a patient or may be unacceptable to the patient. Additionally, surgery may not completely remove neoplastic tissue. Radiation therapy is only effective when the neoplastic tissue exhibits a higher sensitivity to radiation than normal tissue. Radiation therapy can also often elicit serious side effects. Hormonal therapy is rarely given as a single agent. Although hormonal therapy can be effective, it is often used to prevent or delay recurrence of cancer after other treatments have removed the majority of cancer cells.

Despite availability of a variety of chemotherapeutic agents, chemotherapy has many drawbacks. Almost all chemotherapeutic agents are toxic, and chemotherapy causes significant, and often dangerous side effects including severe nausea, bone marrow depression, and immunosuppression. Additionally, even with administration of combinations of chemotherapeutic agents, many tumor cells are resistant or develop resistance to the chemotherapeutic agents. In fact, those cells resistant to the particular chemotherapeutic agents used in the treatment protocol often prove to be resistant to other drugs, even if those agents act by different mechanism from those of the drugs used in the specific treatment. This phenomenon is referred to as pleiotropic drug or multidrug resistance. Because of the drug resistance, many cancers prove or become refractory to standard chemotherapeutic treatment protocols.

Hematological malignancies are cancers that begin in blood-forming tissue, such as the bone marrow, or in the cells of the immune system. Examples of hematological malignancies are leukemia, lymphoma, and myeloma. More specific examples of hematological malignancies include but are not limited to acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), multiple myeloma (MM), non-Hodgkin's lymphoma (NHL), diffuse large B-cell lymphoma (DLBCL), Hodgkin's lymphoma (HL), T-cell lymphoma (TCL), Burkitt lymphoma (BL), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), marginal zone lymphoma (MZL), and myelodysplastic syndromes (MDS).

5. DETAILED DESCRIPTION OF THE INVENTION 5.1 Definitions

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications are incorporated by reference in their entirety. In the event that there is a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

As used herein, and in the specification and the accompanying claims, the indefinite articles “a” and “an” and the definite article “the” include plural as well as single referents, unless the context clearly indicates otherwise.

As used herein, the terms “comprising” and “including” can be used interchangeably. The terms “comprising” and “including” are to be interpreted as specifying the presence of the stated features or components as referred to, but does not preclude the presence or addition of one or more features, or components, or groups thereof. Additionally, the terms “comprising” and “including” are intended to include examples encompassed by the term “consisting of”. Consequently, the term “consisting of” can be used in place of the terms “comprising” and “including” to provide for more specific embodiments of the invention.

The term “consisting of” means that a subject-matter has at least 90%, 95%, 97%, 98% or 99% of the stated features or components of which it consists. In another embodiment the term “consisting of” excludes from the scope of any succeeding recitation any other features or components, excepting those that are not essential to the technical effect to be achieved.

As used herein, the term “or” is to be interpreted as an inclusive “or” meaning any one or any combination. Therefore, “A, B or C” means any of the following: “A; B; C; A and B; A and C; B and C; A, B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or acts are in some way inherently mutually exclusive.

As used herein, and unless otherwise specified, the terms “about” and “approximately,” when used in connection with doses, amounts, or weight percents of ingredients of a composition or a dosage form, mean a dose, amount, or weight percent that is recognized by one of ordinary skill in the art to provide a pharmacological effect equivalent to that obtained from the specified dose, amount, or weight percent. In certain embodiments, the terms “about” and “approximately,” when used in this context, contemplate a dose, amount, or weight percent within 30%, within 20%, within 15%, within 10%, or within 5%, of the specified dose, amount, or weight percent.

As used herein, and unless otherwise specified, the term “pharmaceutically acceptable salts” refers to salts prepared from pharmaceutically acceptable, relatively non-toxic acids, including inorganic acids and organic acids. In certain embodiments, suitable acids include, but are not limited to, acetic, adipic, 4-aminosalicylic, ascorbic, aspartic, benzenesulfonic, benzoic, camphoric, camphorsulfonic, capric, caproic, caprylic, cinnamic, carbonic, citric, cyclamic, dihydrogenphosphoric, 2,5-dihydroxybenzoic (gentisic), 1,2-ethanedisulfonic, ethanesulfonic, fumaric, galactunoric, gluconic, glucuronic, glutamic, glutaric, glycolic, hippuric, hydrobromic, hydrochloric, hydriodic, isobutyric, isethionic, lactic, maleic, malic, malonic, mandelic, methanesulfonic, monohydrogencarbonic, monohydrogen-phosphoric, monohydrogensulfuric, mucic, 1,5-naphthalenedisulfonic, nicotinic, nitric, oxalic, pamoic, pantothenic, phosphoric, phthalic, propionic, pyroglutamic, salicylic, suberic, succinic, sulfuric, tartaric, toluenesulfonic acid, and the like (see, e.g., S. M. Berge et al., J. Pharm. Sci., 66:1-19 (1977); and Handbook of Pharmaceutical Salts: Properties, Selection and Use, P. H. Stahl and C. G. Wermuth, Eds., (2002), Wiley, Weinheim). In certain embodiments, suitable acids are strong acids (e.g., with pKa less than about 1), including, but not limited to, hydrochloric, hydrobromic, sulfuric, nitric, methanesulfonic, benzene sulfonic, toluene sulfonic, naphthalene sulfonic, naphthalene disulfonic, pyridine-sulfonic, or other substituted sulfonic acids. Also included are salts of other relatively non-toxic compounds that possess acidic character, including amino acids, such as aspartic acid and the like, and other compounds, such as aspirin, ibuprofen, saccharin, and the like. Acid addition salts can be obtained by contacting the neutral form of a compound with a sufficient amount of the desired acid, either neat or in a suitable solvent.

As used herein, and unless otherwise specified, the term “prodrug” of an active compound refers to compounds that are transformed in vivo to yield the active compound or a pharmaceutically acceptable form of the active compound. A prodrug can be inactive when administered to a subject, but is converted in vivo to an active compound, for example, by hydrolysis (e.g., hydrolysis in blood). Prodrugs include compounds wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the active compound is administered to a subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively.

As used herein, and unless otherwise specified, the term “isomer” refers to different compounds that have the same molecular formula. “Stereoisomers” are isomers that differ only in the way the atoms are arranged in space. “Atropisomers” are stereoisomers from hindered rotation about single bonds. “Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A mixture of a pair of enantiomers in any proportion can be known as a “racemic” mixture. “Diastereoisomers” are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other. The absolute stereochemistry can be specified according to the Cahn-Ingold-Prelog R—S system. When a compound is an enantiomer, the stereochemistry at each chiral carbon can be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (−) depending on the direction (dextro- or levorotatory) which they rotate plane polarized light at the wavelength of the sodium D line. However, the sign of optical rotation, (+) and (−), is not related to the absolute configuration of the molecule, R and S. Certain of the compounds described herein contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that can be defined, in terms of absolute stereochemistry at each asymmetric atom, as (R)- or (S)-. The present chemical entities, pharmaceutical compositions and methods are meant to include all such possible isomers, including racemic mixtures, optically substantially pure forms and intermediate mixtures. Optically active (R)- and (S)-isomers can be prepared, for example, using chiral synthons or chiral reagents, or resolved using conventional techniques.

“Stereoisomers” can also include E and Z isomers, or a mixture thereof, and cis and trans isomers or a mixture thereof. In certain embodiments, a compound described herein is isolated as either the E or Z isomer. In other embodiments, a compound described herein is a mixture of the E and Z isomers.

“Tautomers” refers to isomeric forms of a compound that are in equilibrium with each other. The concentrations of the isomeric forms will depend on the environment the compound is found in and may be different depending upon, for example, whether the compound is a solid or is in an organic or aqueous solution. For example, in aqueous solution, pyrazoles may exhibit the following isomeric forms, which are referred to as tautomers of each other:

It should also be noted a compound described herein can contain unnatural proportions of atomic isotopes at one or more of the atoms. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium (H), iodine-125 (¹²⁵I) sulfur-35 (³⁵S), or carbon-14 (¹⁴C), or may be isotopically enriched, such as with deuterium (²H), carbon-13 (¹³C), or nitrogen-15 (¹⁵N). As used herein, an “isotopolog” is an isotopically enriched compound. The term “isotopically enriched” refers to an atom having an isotopic composition other than the natural isotopic composition of that atom. “Isotopically enriched” may also refer to a compound containing at least one atom having an isotopic composition other than the natural isotopic composition of that atom. The term “isotopic composition” refers to the amount of each isotope present for a given atom. Radiolabeled and isotopically enriched compounds are useful as therapeutic agents, e.g., cancer therapeutic agents, research reagents, e.g., binding assay reagents, and diagnostic agents, e.g., in vivo imaging agents. All isotopic variations of a compound described herein, whether radioactive or not, are intended to be encompassed within the scope of the embodiments provided herein. In some embodiments, there are provided isotopologs of a compound described herein, for example, the isotopologs are deuterium, carbon-13, and/or nitrogen-15 enriched. As used herein, “deuterated”, means a compound wherein at least one hydrogen (H) has been replaced by deuterium (indicated by D or ²H), that is, the compound is enriched in deuterium in at least one position.

It should be noted that if there is a discrepancy between a depicted structure and a name for that structure, the depicted structure is to be accorded more weight.

As used herein and unless otherwise indicated, the term “treating” means an alleviation, in whole or in part, of a disorder, disease or condition, or one or more of the symptoms associated with a disorder, disease, or condition, or slowing or halting of further progression or worsening of those symptoms, or alleviating or eradicating the cause(s) of the disorder, disease, or condition itself.

As used herein and unless otherwise indicated, the term “preventing” means a method of delaying and/or precluding the onset, recurrence or spread, in whole or in part, of a disorder, disease or condition; barring a subject from acquiring a disorder, disease, or condition; or reducing a subject's risk of acquiring a disorder, disease, or condition.

As used herein and unless otherwise indicated, the term “managing” encompasses preventing the recurrence of the particular disease or disorder in a patient who had suffered from it, lengthening the time a patient who had suffered from the disease or disorder remains in remission, reducing mortality rates of the patients, and/or maintaining a reduction in severity or avoidance of a symptom associated with the disease or condition being managed.

As used herein and unless otherwise indicated, the term “effective amount” in connection with a compound means an amount capable of treating, preventing, or managing a disorder, disease or condition, or symptoms thereof.

In one embodiment, the disorder, disease, or condition has been previously treated one, two, three or four lines of therapy. In one embodiment, the disorder, disease, or condition has been previously treated with two or more lines of treatment, and has less than a complete response (CR) to most recent systemic therapy containing regimen. In some embodiments, the disorder, disease or condition is a hematological malignancy.

In one embodiment, “relapsed or refractory” CLL/SLL may refer to CLL/SLL that has been previously treated with one or more lines of therapy. In one embodiment, the relapsed or refractory CLL/SLL is CLL/SLL that has been previously treated with one, two, three or four lines of therapy.

6.2 Effect of Treatment with Compound 1 in Combination with Second Active Agents on Proliferation of Cell Lines from Hematological Malignancies

A combination study was performed to evaluate the effects on proliferation as a result of treatment with a combination of Compound 1 with compounds tested in hematological malignancies clinically or pre-clinically, based on their mechanism of action, including the following: HDAC inhibitor (panobinostat, romidepsin, and vorinostat), BCL2 inhibitor (venetoclax), BTK inhibitor (ibrutinib), mTOR inhibitor (everolimus), PI3K inhibitor (idelalisib), PKCβ inhibitor (enzastaurin), SYK inhibitor (fostamatinib), JAK2 inhibitor (fedratinib, pacritinib/SB1518, and ruxolitinib), Aurora kinase A inhibitor (alisertib), EZH2 inhibitor (tazemetostat, GSK126, and CPI-1205), BET inhibitor (birabresib and Compound B), hypomethylating agent (5-azacytidine and decitabine), and chemotherapy (bendamustine, doxorubicin, etoposide, methotrexate, cytarabine, vincristine, ifosfamide, melphalan, oxaliplatin, and dexamethasone). Other epigenetic compounds were also tested in this combination study with Compound 1, including DOT1L inhibitor (pinometostat), HAT inhibitor (C646), WDR5 inhibitor (OICR-9429), HDAC6 inhibitor (ACY-241), DNMT1 selective inhibitor (GSK3484862), LSD-1 inhibitor (Compound C), G9A inhibitor (UNC 0631), PRMT5 inhibitor (GSK3326595), BRD9/7 inhibitor (LP99), SUV420H1/H2 inhibitor (A-196), CARM1 inhibitor (EZM2302).

Cell Lines/Cells: Activated B-Cell (ABC) cell lines: TMD-8, SU-DHL-2, OCI-Ly10, RIVA, U2932; and Germinal Center B-cell (GCB) cell lines: SU-DHL10, Pfeiffer, WSU-DLCL2, SU-DHL4, DB; myeloma cell lines: H929, JJN3 and SK-MM1; acute myeloid leukemia cell line: HNT-34; acute lymphocytic leukemia cell line: Karpas-231; other lymphoma cell lines: Daudi, Karpas-299, HuT-102, L-428.

Experimental Procedures: The concentrations of Compound 1 used in the dose response curves (DRC) were selected on the basis of the sensitivity of the cell line in anti-proliferative assays. U2932, SU-DHL4, Pfeiffer, RIVA, DB, Daudi, H-929, HNT-34, JJN3, Karpas-299, Karpas-231, HuT-102, L-428 and SK-MM1 were treated at high Compound 1 starting concentrations (starting at 10 M); TMD-8, SU-DHL2, SU-DHL10, WSU-DLCL2, and OCI-Ly10 were treated at low Compound 1 concentrations (starting at 1 M). All Compound 1 solutions were serially diluted in 3-fold steps for a 10-point dilution curve. Alternatively, combination compound solutions were serially diluted from 5 M starting concentration and serially diluted 6-fold for a 6-point dilution curve. Compounds were plated in a 384-well plate where Compound 1 was dispensed in rows and the combination compound agent in columns. The same concentration of Compound 1 or combination compound was distributed amongst its row or column respectively to create a matrix of compound combinations. Cells were added to each well and cultured for 3 days. For some epigenetic compounds (tazemetostat, GSK126, CPI-1205, 5-azacytidine and decitabine), cells were pretreated for 4 days with the epigenetic compound before starting treatment with Compound 1. After those 4 days, cells were treated with the combination of Compound 1 and the epigenetic agents, as previously described for the other compounds. For some other epigenetic agents (EPZ5676, C646, OICR-9429, ACY-241, GSK3484862, Compound C, UNC 0631, GSK3326595, LP99, A-196, CARM1 EZM2302) cells were cultured for 5 days due to their mechanism of action.

Cell Preparation and Treatment: Compound 1 was dispensed in 384-well plates and frozen at −80° C. until the start of the experiment. Plates were either made at a concentration of 10 M or 1 M diluted 3-fold for a 10-point dilution curve, with a final DMSO concentration of 0.2%. All cell line solutions were diluted to a concentration of 100,000 cells/mL and added to each well in a volume of 50 L, with the exception of SU-DHL-6 solution, which was diluted to 25,000 cells/mL. At the end of the treatment period cells were lysed with Cell Titer Glo (CTG) reagents following manufacture recommendation. Luminescent signal was read using an Envision and data was normalized by DMSO for data analysis.

Data Analysis: The combination effect was analyzed by combining results from Highest Single Agent (HSA) and Bliss Independency methods. See, e.g., Foucquier J, Guedj M., Analysis of drug combinations: current methodological landscape. Pharmacol Res Perspect. 2015;3(3):e00149. doi:10.1002/prp2.149.

Results: Effect of treatment with a combination of Compound 1 with 43 compounds was evaluated by CTG after 3 and 5 days of co-treatment of 19 cell lines from hematological malignancies, including DLBCL cell lines with different sensitivity to Compound 1 (FIG. 1). Combined results of HSA and Bliss scores were used to define synergistic and additive effect of the combinations.

A wide range of additive or synergistic effects was observed across selected cell lines. All tested combinations showed additive (light grey) or synergistic (dark grey) effects in at least one of the 19 cell lines tested, independently of Compound 1 activity on proliferation of those cell lines (FIG. 2). Treatment of very sensitive cell lines such as JJN-3, SU-DHL2 or SU-DHL10 showed synergistic effects when treated with Compound 1 and a number of compounds including panobinostat, romidepsin, vincristine, everolimus, fedratinib, alisertib, and birabresib. Even more Compound 1 resistant cell lines such as DB, HNT-34 or SU-DHL4 also showed this benefit when Compound 1 was combined with a number of compounds including panobinostat, etoposide, vincristine, venetoclax, ibrutinib, everolimus, enzastaurin, tazemetostat, GSK126, CPI-1205, 5-azacytidine, and decitabine.

All disease subtypes tested (lymphomas, leukemias and multiple myeloma) benefited from the combination treatments of clinically relevant compounds or other epigenetic agents with Compound 1.

Female SCID mice were inoculated subcutaneously with WSU-DLCL2 cells in the flank region above the right hind leg. Following inoculation of animals, the tumors were allowed to grow to approximately 200 mm³ prior to randomization. On day 14 following tumor cell inoculation, the mice bearing WSU-DLCL2 tumors ranging between 150 and 250 mm³ were pooled together and randomized into various treatment groups. Compound 1 was formulated in 0.5% Methyl Cellulose, 0.25% Tween 80 and 50 mM Citrate pH 3 in water. 5-Azacytidine was formulated in 0.9% saline. Compound 1 (1 mg/kg) was orally administered with three cycles of once daily for 5 consecutive days followed by 2 days off starting from day 14 after tumor cell inoculation. 5-Azacytidine (1 mg/kg) was intraperitoneally administered once a day (QD) for three weeks. In combination group the animals received Compound 1 (1 mg/kg/5D on/2D off) and 5-azacytidine (1 mg/kg, QD) simultaneously for three weeks starting from day 14 after tumor cell inoculation. Tumors were measured twice a week using calipers and tumor volumes were calculated using the formula of W²×L/2. Statistical analysis was performed using a one-way or 2-way analysis of variance (ANOVA). Synergy calculations were performed using fractional product method.

Results & Conclusions: Compound 1 (1 mg/kg) and 5-azacytidine (1 mg/kg) were tested as single agents and in combination in WSU-DLCL2 xenograft model. As a single agent Compound 1 significantly (p<0.0001) inhibited (45.6%) WSU-DLCL2 DLBCL tumor growth. 5-Azacytidine as single agent marginally (−20.1%) inhibited WSU-DLCL2 DLBCL xenograft tumor growth (FIG. 3). Compound 1 at 1 mg/kg when administered in combination with 5-azacytidine 1 mg/kg yielded a significant (p<0.0001) decrease in tumor volume when compared with vehicle control, displaying a tumor volume reduction of 74% compared to vehicle control (FIG. 3). In a 2-way ANOVA with Bonferroni's post-test, this combination antitumor activity was significantly better than Compound 1 alone (74% versus 45.6% TVR; p<0.0001) or 5-azacytidine alone (74% versus 20.1% TVR; p<0.01). Using the fractional product method, the combination antitumor activity of Compound 1 at 1 mg/kg and 5-azacytidine at 1 mg/kg was determined to be synergistic in decreasing tumor volume.

In conclusion, Compound 1 in combination with 5-azacytidine exhibited synergism in reducing tumor volume in the WSU-DLCL2 DLBCL xenograft tumor model.

6.6 Antiproliferative Effect of Compound 1 in Combination with Venetoclax in B-Cell CLL Patient Cells

CLL is characterized by accumulation of clonal CD5⁺CD19⁺ lymphocytes resistant to apoptosis. Venetoclax blocks the anti-apoptotic B-cell lymphoma-2 (Bcl-2) protein, leading to programmed cell death of CLL cells and is currently being tested in the clinic with different combinations for relapsed refractory patients. The effect of Compound 1 in combination with venetoclax on the proliferation and survival of CLL B cells was assessed utilizing an ex vivo model where primary CLL cells from patient-derived blood were stimulated to proliferate with 10% fetal bovine serum (FBS), 5 ng/mL recombinant human interleukine-4 (rh IL-4), 10 ng/mL recombinant human interleukine-10 (rh IL-10) and co-cultured with fibroblast expressing surface CD154 (CD40L) in a 96 well plate format.

Peripheral blood mononuclear cells (PBMCs) from CLL patients (Table 6) containing 52%-86% of CD5⁺CD19⁺ tumor cells were cultured at a density of 0.06-0.1×10⁶ cells/well on a monolayer of CD154-expressing fibroblasts at a density of 0.09×10⁶ cells/well in 96-well plates in RPMI 1640 medium supplemented with 10% FBS, 5 ng/mL rh IL-4 and 10 ng/mL rh IL-10 and were simultaneously treated with vehicle control (0.1% DMSO) or increasing concentrations of Compound 1 ranging from 0.0001 to 1 μM and venetoclax at concentrations ranging from 0.001 to 10 μM across all the different concentrations of Compound 1. After 144 hrs of treatment with both the agents, flow cytometric analysis was used to determine the number of tumor cells that were viable or apoptotic.

After 6 days of treatment, the tumor cell count was assessed by staining the patient PBMCs in each condition with tumor cell surface markers CD5 & CD19 along with Live/Dead fixable dye to exclude the dead cells and followed by intracellular staining for Caspase 3 antibody to identify the apoptotic cells and was measured by flow cytometry (Attune N×T, Thermo Fisher). The live tumor cell count for each condition was calculated by normalizing to the precision count beads added to each sample.

TABLE 6 Characteristics of the CLL Samples Used. Tumor IGHV Mutation CLL Pt Burden Status Cytogenetics Prior Therapy 11 85% Non-Mutated del(13q) N 12 75% Non-Mutated del(13q) (35%) N 13 30% Mutated del(13q); tri12 N 14 86% Mutated del(13q); anamoly in Mitomycin cell interphase (86%)

The live tumor cell count was then normalized to the DMSO control (considered as 1000%) to calculate the percentage of viable cells remaining after treatment. The normalized percentage of tumor cells was then represented as heat map using Graph Pad Prism 8.0.0 to indicate the degree of tumor toxicity for each of the combinations (FIG. 6).

For apoptosis analysis, the percentage of apoptosis combining both “early” (Caspase 3 positive and Live-Dead fixable dye negative) and “late” apoptosis (Caspase 3 and Live-Dead fixable dye positive) cell gates subtracting the baseline DMSO value was graphed using GraphPad Prism 8.0.0.0. The Y_(max) (maximal percentage of apoptos is achieved) values from apoptosis curves were calculated by performing a nonlinear regression curve fitting using log(agonist) vs. normalized response—Variable slope analysis and identifying the maximum value on GraphPad Prism 8.0.0 (Table 7).

6.7 Antiproliferative Effect of Compound 1 in Combination with Ilbrutinib in B-cell CLL Patient Cells

CLL is characterized by accumulation of clonal CD5+CD19⁺ lymphocytes resistant to apoptosis. Ibrutinib is a selective inhibitor of Bruton's tyrosine kinase (BTK), which is a signaling molecule of the B-cell antigen receptor (BCR). It is currently the first line treatment for newly diagnosed CLL patients and is being investigated in different combinations for relapsed patients. The effect of Compound 1 in combination with ibrutinib on the proliferation and survival of CLL B cells was assessed utilizing an ex vivo model where primary CLL cells from patient-derived blood were stimulated to proliferate with 10% fetal bovine serum (FBS), 5 ng/mL recombinant human interleukine-4 (rh IL-4), 10 ng/mL recombinant human interleukine-10 (rh IL-10) and co-cultured with fibroblast expressing surface CD154 (CD40L) in a 96 well plate format.

Peripheral blood mononuclear cells (PBMCs) from CLL patients (Table 8) containing 52%-86% of CD5⁺CD19⁺ tumor cells were cultured at a density of 0.06-0.1×10⁶ cells/well on a monolayer of CD154-expressing fibroblasts at a density of 0.09×10⁶ cells/well in 96-well plates in RPMI 1640 medium supplemented with 10% FBS, 5 ng/mL rh IL-4 and 10 ng/mL rh IL-10 and were simultaneously treated with vehicle control (0.1% DMSO) or increasing concentrations of Compound 1 ranging from 0.0001 to 1 μM and ibrutinib at concentrations ranging from 0.001 to 10 μM across all the different concentrations of Compound 1. After 144 hrs of treatment with both the agents, flow cytometric analysis was used to determine the number of tumor cells that were viable or apoptotic.

The tumor cell count was assessed by staining the patient PBMCs in each condition with tumor cell surface markers CD5 & CD19 along with Live/Dead fixable dye to exclude the dead cells and followed by intracellular staining for Caspase3 antibody to identify the apoptotic cells and was measured by flow cytometry (Attune N×T, Thermo Fisher).

Experimental procedures: CellTiter-Glo (CTG), a luminescent dye that measures adenosine-5′-triphosphate (ATP), was used to quantify the cell proliferation across a panel of 40 unique DLBCL cell lines. Single agents and combinations were pre-spotted into 384-well plates (diluted in final dimethyl sulfoxide [DMSO] concentration of 0.1% for a maximal volume of 50 L). A 10-point dose response that includes a DMSO point for single agent Compound B (10 μM top, 3-fold serial dilution) and Compound 1 (10 μM top, 3-fold serial dilution for 16 lines and 1 M top, 4-fold serial dilution for 24 lines) were tested for the cell line panel and the 10×10 combination matrices utilized the same respective dose-response series as single agent. Inter-plate duplicates were utilized for all treatment conditions.

For each DLBCL cell line, 50 L of cell suspension at their respective seeding densities of 0.025 to 0.2×10⁶ cells per mL were added to 384-well plates containing the compounds. The effect of the single agents and combinations on the proliferation/viability of cells was assessed after 5 days of incubation. Twenty-five microliters of CTG per well was then dispensed to the cell suspension, and ATP released by viable cells was measured after a 30-minute incubation as relative luminescence units (RLU) using an EnVision plate reader (PerkinElmer, Covina, Calif.). Single-agent and combination-mediated cytotoxicity is indicated by a lower ATP level in the media after 5-day incubation with drug compared to the Day 0 ATP level.

Data analysis: Percent growth was calculated by the equation “% Growth=(Day 5 CTG−Day 0 CTG)/(Day 0 CTG).” All data was analyzed by GraphPad Prism 7 with the XY analyses nonlinear regression curve fit using the parameters for “log(inhibitor) vs. response—Variable slope (four parameters).” Cytotoxicity was called if any part of the DRC CTG signal went below the Day 0 CTG read and cytostatic effects were indicated by the DRC CTG signal staying above the Day 0 line. Combination data was analyzed with the Bliss independence model for synergy and Highest Single Agent (HSA) model for additivity with p-values <0.01 to be considered significant.

Conclusion: The results are shown in FIG. 8. Combinations of Compound B and Compound 1 showed synergy and additivity in the majority of DLBCL cell lines with no subtype specificity.
